              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
DIS red side was displaying the warm electronic issues we were seeing a few weeks ago again.  It was pretty warm today outside and up in the dome, so maybe not too surprising.
I needed to do a nicfps init as well.  Black/white bar in the test images. This fixed the problem.
Clouds moved in around 04:30 and my observer was no longer able to observe on sky.  I decided to close as there was some possible radar returns approaching and it was completely cloudy.
